Windows 10: photo preview only working on some

have checked that setting to only show the preview not icons.

Preview Pane for Images/Some Thumbnails/Photos not Working Only on OneDrive Folder

The preview pane and thumbnails as well as the Photos app are not working, but only on my OneDrive folder. It works fine on an exact copy of the same files that are not in the OneDrive synced folder structure (and known to Windows as being OneDrive).

• Open OneDrive Folder, navigate to photos directory
• Sony Raw images (.ARW) do not show thumbnails. (I have the Sony plug in installed)
• Double click on a raw file, Photos says "We can't open this file."
• Click on a jpeg file, and with preview window turned on, no preview appears
• Double click on jpeg file, opens fine in Photos, and then the preview window image appears

• Navigate to a directory that is not synced to OneDrive
• Sony Raw thumbnails show up fine. They also show up in the preview window.
• Double click on Raw file and Photos opens it up without problems

• Back to OneDrive photo directory
• Copy raw file to desktop
• Immediately the thumbnail appears and the file can be opened with Photos. The same file that it can't open from Explorer in the OneDrive directory

This is only happening on my desktop. My laptop is fine. Both same versions of Windows 10 Version 1709 OS Build 16299.19

 

Only some photos will preview in explorer

Recently, when importing photos from my digital camera into the pictures folder, only some of the photos will preview with a thumbnail. Initially, almost none of the photos will show as a thumbnail, only as icons, but as time goes on, more photos will
show as preview thumbnails. All of the pictures are from the same import, so there is not a difference in setting or file type.

Photo Previews in Windows 10 not working over a network connection

Recently this summer after a Windows 10 update, we can only see partial photo previews over a shared network connection while it works fine on a local drive for the most part. I have tried all suggestions I have seen on the web including:

• making sure that the folder optimization type is "Pictures"
• clearing the thumbnail cache
• making sure the Folder/File View option "Always show icons, never thumbnails" is unchecked
• changing the default photo app to something else does nothing either

This is incredibly frustrating for our users who work with photos. Does Microsoft have a fix for this and if not, how soon will they have it?
